DESCRIPTION
The 42117 series of fixed voltage regulators covers the output voltage range from -5 VDC through -30 VDC. These voltage regulators are fabricated using hybrid techniques and will operate at case temperatures up to +200 °C. These devices are complete with internal short circuit protection which includes voltage shutdown and current foldback. The 42117 series voltage regulators normally do not require any additional components. However, for good design practice, an external filter cap of 2 µF should be installed at the input, as close to the case as possible. ABSOLUTE MAXIMUM RATINGS AT 200°C CASE TEMPERATURE Typical Connection Diagram Note: D1 should be installed for input safety INPUT OUTPUT - COMMON - 2uf + + + RECTIFIED VOUT REGULATED AS REQUESTED VIN AS REQUESTED HEADER
